The invention relates to a method for operating a regenerative bipolar membrane fuel cell and regenerative bipolar cell for storing and generating energy. The method according to the invention comprises: - providing a regenerative bipolar membrane fuel cell comprising: - a reactor with an anode compartment having an anode and a cathode compartment having a cathode; and - a number of cell units separating the anode and cathode compartments, wherein the cell unit comprises an anion exchange membrane, a cation exchange membrane, and a bipolar, with the membranes defining compartments; - providinga fluid on both sides of the bipolar membrane with ion concentrations such that water activity difference between the fluids on both sides of the bipolar membrane is minimized; - storing energy in anenergy storage state by providing an external current to the reactor such that a p H difference between fluids in contact with the bipolar membrane is achieved; - switching between the energy storagestate and an energy generation state; and - regenerating energy in the energy generating state from the p H difference between fluids in contact with the bipolar membrane.
Description
technical field [0001] The present invention relates to a method of operating a regenerative bipolar membrane fuel cell capable of storing and generating energy. This enables storage of energy during periods of excess energy and use of this energy during periods of energy deficit. Temporary storage of energy is important for matching energy supply and demand as well as for peak adjustment of energy demand. For example, this enables the storage of energy from supplies such as solar, wind and hydro. Background technique [0002] Conventional energy storage devices include batteries, which cannot provide sustainable energy storage in the long run due to declining reserves of many important elements needed for battery production. [0003] Conventional energy generation methods may involve the use of electrolyte differences for a reverse electrodialysis process (RED), as described in WO2007 / 094659. For example, this difference is reflected between sea water and river water. T...
